My invention relates to valves. It is the object of my invention toprovide a fixture for v. controlling with v a single handlethedireCtingof water toa tub or shower and forproviding `for the mixing of a hot andcold waterfor suchtub or shower in jai mixing chamber in thel fixture.

Y It is my object to provide a very large mixingfehamber relative to theentirel fixture so 1.0.tlfiatclomplete mixing may be secured, irre--spective of .the speed orpressure of the water. Itis a further objectof `this xture to eliminate Springs and the like. Y

It is my obj ect to provide means of simul- 15) taneouslyl openingl andclosing two valves withv a single handle and a single mov-ement.

Itis a further yobject tov y'provide a fixture in whichsuchlvalvemechanism may be removed bodily from the -xture without the necessity e2g of disturbing the fixture.

It an additional object of providing means of spacing the fixture from aface plate carried on theI tile wall insuch a manner that `the fixturemaybe adjusted .to any distance from the-tilewall to the'xture and toany i i depth ofwall.I

Referring Ytothe drawings: n "ligurev 1 is a section through the fixturewith the shower valve closed andv the tubv valveop'en.Vv Y V' v Figure 2lisa similar view with the shower valve'open and the tub valve closed.

Figure 8 is a section on the line 3-3 of! Figur`e 1,showing theyadjustable feature be- ,3 tween the plate andthe fixture. e rFigure4is'a section on the line of Figure l, Y

Figure is a section on the line 5-5 of FigureLj- A' y Referringto thedrawings, it will be understood that'this fixture is of just the size tofit between two studdings' and is jso arranged as to b'eadaptable tosucha .compactlocation.,

It is also relatively shallow so that it can be! installed in a narrowspace in a thin-wall; The opening through which the fixture is insertedin the wall is closed by a single plate,

designated 1,'engaging with the 'til-e wall 2.

Thus the ventire fixture maybe moved through 50 the opening 3 in thewall when the plate 1 is removed, but if it is not desiredto remove thefixture the valve mechanism, hereinafter described, may be movedoutwardly'by detaohing a single screw collar 4 mounted on l the threadedsleeve 5 of the `fixture casing 6,

The Veasing Gis provided with a hot water inlet passageway 7 emptyinginto the mixing y chamber 8. Suchy passagewayis controlled by a valvemember, the stem generally designated 9, of any desired character. Onthe stem is mounted a threaded spacing sleeve 10 threaded into thebearing sleeve 11 carried on the casing 6 andcarrying at its outer endthe internally threaded sleeve 12 having the bezel 13 fitting on theouter face of the platel .1. This exteriorly smooth sleeve 12 fitswith-` inthe opening 14 inthe plate 1 toreceiveiit. Thedistance betweenthe plate and the fixture may be adjusted by Vthreading the sleeve 10into sleeve 12to suitable positions. If the sleeveV 10 is too long itcan be .cut od bya plumber.

Returning to theixture proper, a similar j construction is found onv theleft-hand yofthe fixture for the cold water which Venters through thepassageway 15 into the mixing chamber 8. The mixed fluid fromvthe chamjn ber may either pass upwardly to the shower ythrough thevport 16 intothe showerpassagej way 17 orit may pass through the port 18jv intothetub passageway 19. The valve mem: bers forcontrolling thesepassageways 16, and j 18 are arranged as follows: The controlshaft 20havingahandle 21 is loosely mounted in a threade'dlsleeve 4.1A'packingsleeve 22 is mountedfon the 'exterior of the sleeve 4 and rej `tains inpositionV a packing23. Thisfsleevegll carries an `interiorlydisposedpin-,24, which projects .into a1passageway 25 in the tubvalve 26.VV Thistub valve is threaded upon the threads27 of the shaft 20. The tub valve26 cannot rotate due to thepin 24, but it can reciprocate being guide-din its'reciprocationA by pin 24. The rotation of the shaft 20 andscrew27 will cause this reciprocation of ther tub valve 26 and Vcause itto either engage or4 `disengage the tub valve seat 28 opening andclosing the port 18. y Y A The tub valve member 26 is provided withsleeve 29 externally threaded at 30, on which ico that when the valve isseated the valve memj ber 34 remains stationary when the valve shaftrotates as is necessary for the operation of the tub valve. It is movedto engaging and disengaging positionsfby' reason of the screw 27 of theshaft 20worlzing within the tub valve member 26 which, when held in astationary position relative to any rotating movement by reasonof thepin 24, will provide the proper thread for causing thismovement throughthe shaft 20 ofthe shower valve y member 24.rv l i It will be understoodthat I desire to comprehend within my invention such .modifications asmay be necessary to adapt it to varying conditions and uses.

Having thus fullydescribed Vmy invention, what I claim as new and desireto secure by Letters Patent, is:

1; Inv a fixture, a mixing chamber having a shower port and a tub port,yan actuating shaft, a. tub valve member threaded on said fshaft, meansto prevent the rotation vof said valve member but to permit itsreciprocation by the shaft, and a rotating shower valve member carriedon said shaft.
